Those worked before, so apparently there is a bug regarding #, +, . with the client-side JavaScript, as those divs don't get the correct class (e.g. question-summary tagged-interesting).(with my limited web-dev-fu it looks like the client-side function getTagsSelector(d)might be the culprit)

Nope, I have C# as a tag as well as .NET and no C# nor .NET questions are being highlighted. Wait, nevermind. Had to un-script-block netdna-cdn.com for it to work. Is this recent?
